“…A B100 based on rapeseed oil produced a decrease of about 10% in the effective power and torque of the engine, plus an increase in the specific fuel consumption due to the lower calorific value of the fuel [23]. To improve these parameters, sometimes additives are added to the blend to improve torque, power and mean effective pressure when using biodiesel [24].…”

Diesel engines have dominated the heavy duty and passenger vehicle market in the past 30 years. Consequently, the oil-derived fuels demand and the amount of pollutant emissions have witnessed exponential growth during the last three decades. Although Diesel engines present the advantage of higher efficiency and, therefore, lower levels of CO2 emissions, they produce high levels of NOX and particulate matter. In order to face these difficulties, the use of alternative fuels started booming in the early 2000s and continue to gain influence today. Biodiesel stands out from the alternative fuels’ selection for its ease of use, production, storage and potential to reduce levels of particles, CO, HC and CO2. The main goal of this research is to experimentally determine the influence of palm oil biodiesel produced in Colombia on a Diesel engine’s behavior in terms of engine performance and pollutant emissions. As different mixtures of commercial Diesel and biodiesel at different operating conditions were tested, the results showed that it is possible to maintain the engine’s performance at acceptable levels and to, in some cases, reduce smoke density and NOX levels.

“…pine oil, algae driven oils) is subject to a magnetic field and chemical reactions simultaneously. The physicochemical processes can be hosted by micro-or macrochemical reactors [5,6]. Often, biofuels have strong non-Newtonian characteristics, and thus the problem includes interactions amongst non-Newtonian fluids, magnetic fields, heat of reactions and transport processes associated with fuel reforming.…”

Magnetic microfuel-reforming is a promising method of biofuel processing in diesel engines. However, the complex interactions amongst the non-Newtonian biofuel flow, magnetic field and reactor have hindered understanding of their influences upon the transport phenomena in the system. To resolve this issue, the transport of heat and mass in a porous microreactor containing a Casson rheological fluid and subject to a magnetic field is investigated analytically. The system is assumed to host a homogenous and uniformly distributed endothermic/exothermic chemical reaction. Two-dimensional analytical solutions are developed for the temperature and concentration fields as well as the Nusselt number and local entropy generations, and the results are rigorously validated. It is demonstrated that changes in the non-Newtonian characteristics of the fluid and altering the magnetic and thermal radiation properties can lead to bifurcation of temperature gradient on the surface of the porous medium. The general behaviour of such bifurcation is dominated by the exothermicity (or endothermicity) of the chemical reaction in the fluid phase. It is also shown that variations in the Casson fluid parameter and changes in the intensity and incident angle of the magnetic field can modify the Nusselt number considerably. The extent of these modifications is found to be heavily dependent upon the wall thickness and diminishes as the walls become thicker. Further, the total entropy generation is shown to be highly sensitive to the wall thickness and increases by intensifying the magnetic field, provided that the microreactor walls are thin.
